OPERATION
TYRE PRESSURE
Tyre pressure must be considered when adding
weight to the tractor. The following “TYRE
INFLATION vs PERMISSIBLE LOAD” table lists the
tyre sizes available and shows the maximum load the
tires can carry for a given air pressure. Note that the
load capacities decrease as inflation pressures
decrease, and also that a specific tyre pressure is
recommended for certain size tyres.
TYRES
Inflation and Service
•
Upon receiving your tractor, check the air
pressure in the tires as indicated in the tables.
• Check tyre pressure every 50 hours, or weekly.
• Tyre inflation pressure affects the amount of
weight which a tyre may carry. Locate the tires
for your tractor in the “TYRE INFLATION vs.
PERMISSIBLE LOAD” chart on page 29. Do
not over-or-under inflate the tires.
• Do not inflate a tyre above the manufacturer’s
maximum pressure shown on the tyre or the
maximum pressure shown in the “TYRE
INFLATION vs. PERMISSIBLE LOAD” chart,
page 29 if the tyre is not marked.
• Do not inflate a tyre that has been run flat or
seriously under-inflated until the tyre has been
inspected for damage by a qualified person.
• When checking tyre pressure, inspect the tyre
for damaged side walls and tread cuts.
Neglected damage will lead to early tyre
failure.
WARNING: Inflating or servicing tires
can be dangerous. Trained personnel
should be called to service and/or
mount tires when possible. In any event
to avoid possible serious or fatal injury,
follow the safety precautions below:
• Be sure the rim is clean and free of rust.
• Lubricate both tyre beads and rim flanges with
soap solution. Do not use oil or grease.
• Use a clip-on tyre chuck with a remote hose
and gauge which allows the operator to stand
clear of the tyre while inflating it.
• NEVER INFLATE TO OVER 35 psi (2.4 bar)
TO SEAT BEADS. If beads have not seated
by time pressure reaches 35 psi, deflate the
assembly, reposition tyre on rim, relubricate
both tyre beads and rim flanges and re-inflate.
Inflation beyond 35 psi with unseated beads
may break the bead or rim with explosive
force sufficient to cause serious injury.
• After seating the beads, adjust inflation
pressure to recommended operating
pressure.
• Do not inflate a tyre unless the rim is mounted
on the tractor or is secured so that it will not
move if the tyre or rim should suddenly fail.
• Do not weld, braze, otherwise repair, or use a
damaged rim.
• Never attempt tyre repairs on a public road or
highway.
• Use jack stands or other suitable blocking to
support the tractor while repairing tires.
• Insure jack has adequate capacity to lift your
tractor.
• Insure jack is placed on a firm level surface.
• Do not put any part of your body under the
tractor or start the engine while the tractor is
on the jack.
• Torque lug nuts to specification after
reinstalling wheel. Check lug nut torque daily
until torque stabilizes.
• Refer to tractor weighting section before
adding ballast to the tires.
